Constants

FileFsVolumeInformation Return a FILE_FS_VOLUME_INFORMATION structure that contains information about the volume such as the volume label, serial number, and creation time.
FileFsLabelInformation Use a FILE_FS_LABEL_INFORMATION structure to set information a volume label.
FileFsSizeInformation Return a FILE_FS_SIZE_INFORMATION structure containing information about the amount of space on the volume that is available to the user that is associated with the calling thread.
FileFsDeviceInformation Return a FILE_FS_DEVICE_INFORMATION structure that contains device information for the volume.
FileFsAttributeInformation Return a FILE_FS_ATTRIBUTE_INFORMATION structure that contains attribute information about the file system responsible for the volume.
FileFsControlInformation Return a FILE_FS_CONTROL_INFORMATION structure that contains file system control information about the volume.
FileFsFullSizeInformation Return a FILE_FS_FULL_SIZE_INFORMATION structure that contains information about the total amount of space available on the volume.
FileFsObjectIdInformation Return a FILE_FS_OBJECTID_INFORMATION structure that contains file-system-specific object ID information for the volume. Note that this is not the same as the (GUID-based) unique volume name that is assigned by the operating system.
FileFsDriverPathInformation Return a FILE_FS_DRIVER_PATH_INFORMATION structure that contains information about whether a specified driver is in the I/O path for the volume. The originator of the IRP_MJ_QUERY_VOLUME_INFORMATION request must store the name of the driver into the FILE_FS_DRIVER_PATH_INFORMATION structure before sending the IRP to the file system volume device stack.
FileFsVolumeFlagsInformation Use a FILE_FS_VOLUME_FLAGS_INFORMATION structure to set the flags for a volume.
FileFsSectorSizeInformation Return a FILE_FS_SECTOR_SIZE_INFORMATION structure that contains information about the physical and logical sector sizes of a volume.
FileFsDataCopyInformation Returns a FILE_FS_DATA_COPY_INFORMATION structure that contains the number of data copies.
FileFsMetadataSizeInformation Returns a FILE_FS_METADATA_SIZE_INFORMATION structure that contains the metadata size information.
FileFsFullSizeInformationEx Returns a FILE_FS_FULL_SIZE_INFORMATION_EX structure that contains information about the total amount of space available on the volume.
FileFsGuidInformation Returns a FILE_FS_GUID_INFORMATION structure tha contains the GUID information.
FileFsMaximumInformation End of this enumeration.
